Just out of curiosity, how do you make those measurements at the antenna
without your body affecting the results? On many antennas it is almost
impossible to position yourself at the feed point anyway, and in any case,
isn't it the whole system (antenna, support, feed line, etc.) we are really
concerned with? Who cares where an antenna with no feed line resonates
(other than the theoreticians). Not a criticism of your comment, Don, I
believe you are correct in what you say, but what does it really mean?

Where did you make those measurements?
If at the shack end of the coax, they are quite meaningless as to
antenna resonance.
The only way to get the correct measurements is AT THE ANTENNA.
Sorry, but too many guys/gals put their SWR meters at the shack end of
the coax and try to determine what the ANTENNA looks like from there.
It just doesn't work that way.
